Okay, got to say up front that I donāt have time to dig too much into details, but I want to share my thoughts on using Nextcloud as an organizational suite over a number of yearsā¦
Files
- Iāve found it best to keep files very limited, no more than a couple gigabytes of files ever available to a user in the cloud.
- Everything is automatically moved into backups and cold storage via cron automation and rsync.
- Nothing important ever lives āonlyā in Nextcloud.
- Sync is not a backup solution, nor should it be.
- Everything available to the user relates to particular core fields of interest
- It isnāt possible to relate different apps together in an ad-hoc manner, so I turn to a combination of Qownnotes API + Notes app, Joplin
- Cryptomator is the only trust worthy e2e tool Iāve ever used across all mobile and desktop devices.
- Auto-uploads are managed via syncthing, as user www-data and localstorage, due to the nature of how large and numerous my files can be. This helps minimize two factors:
- Less things to upload on the clients, plus it is faster
- No dependence on a central server, including my own. Device to device is fine and skips webdav sync altogether.
- It is easy to be disorganized since Nextcloud does not understand my organization methods in any straightforward way via tags or between FIles and other apps.
- Iāve found it best to manage directly into cold storage
- Only those things Iām actively sharing, referencing, and waiting for as uploads (via webui) reside in Nextcloud at any time.
Groupware - Deck, Calendar, Tasks
Deck is a great tool for organization purposes, but it is still impossible to export or import as you might in Google Takeout. This makes me unable to trust the app entirely and I never leave valuable information in it alone.
Repetition is extremely tedious with Nextcloud, because it doesnāt understand that everything Iām doing is related to a particular tag or a particular date or anything recurringā¦ this makes it very, very easy to make errors. Or, it makes the process of inputting data quite slow.
For this reason, Iāve found critical collaboration with money on the line must go through Google Drive. Trust me, Iāve been trying to years to not do this, but from Gmail you have the option to not only save files / folders to the correct place, but also move and organize them without leaving Gmail.
- This is vastly superior to moving between tabs in a browser.
- For all itās evil, Google understands the events and tasks Iām inputting are related or recurring, which cuts down my time at the computer by rough 95%. It also reduces my risk of errors by 100% because it goes so far as assuming the dates / times / references Iām using.
- Unfortunately, I must use such a system if being late or lacking the necessary information will cost me money.
I cannot trust myself to set a recurring schedule for myself (let alone others) with basic information like:
- Event recurring every two weeks from x to y time.
- Bob and Susan are co-host.
- Everyone must arrive 60 minutes before.
- I must be reminded two days before to prepare.
- Attached are the directions.
- Description includes who to contact in the event anything goes wrong.
- Attached are tasks which must be completed to prepare.
- If I fail to include any of the above, I risk losing my job.
In theory this could be simple to do, but I cannot trust myself to manually input the 9 things above for each and every calendar entry in Nextcloud. It would be career suicide.
Tasks is much easier to manage, imo, but it lacks the flexibility of Deck. And, again, Iām unable to auto-associate anything as mentioned above.
To get around this, I like to use Nextcloud for long-term planning, such as unconfirmed events that are in a planning stage. But, once the event is happening, I must move to Google Drive. Only the most sensitive details, such as a contract, would be shared from Nextcloud with an expiration link. Or as a way for guests to upload folders and documents.
Talk
Talk is of no use to me personally, because my primary discussion interest for personal chat would be through a fully e2e, federated, bridged tool such as Matrix. Matrix already includes every major project there is (besides Nextcloud) and Iāve been on it for many years. I see zero advantage to leaving [Matrix] when it makes it possible for me to connect to any other hosted Matrix and IRC server from a self-hosted server. This already covers ever open source project chat Iām interested in, so I see no need to leave that eco-system as a more general way to engage in open source conversations.
Also, I prefer to keep my Nextcloud focused on getting things done, which means as close to no conversation as possible. Since comments have not seen further development, I find it better to post share links into Matrix if input is needed. Or, I would consider Rocket.chat since it is a totally fantastic drop-in replacement to Slack, which works beautifully and includes all major features I desire (Matrix integration, webdav integration, Slack replica interface, bot support, rss support and comprehensive guest/anonymous access).
Notes
As you can find on the forum, weāve spent years trying to get out of Evernote. I have many years of fantastic content, which were drag and dropped into Evernote and very nicely organized with tags, reminders, photos and audio notes. The only way to keep this information intact was by migrating it into Joplin, as it will render properly. For the foreseeable future, that is where it will stay. I do not find Joplin to be as easy to use as Evernote was, but it includes a level of functionality that cannot be beat, especially since everything is presented exactly as it is in Evernote.
Markdown notes work well enough for programmer like text tasks, but for multimedia I still have not found a replacement for Evernote or more ādrag and dropā visual approaches to work flows where lots of random media, pictures, attachments are concerned.
Thanks for reading!
Thanks if you read this far. I realize there is much more to discuss, but thought Iād mention it as I encounter these obstacles yet again, even as an obvious enthusiast, while attempting to organize my projects. 
) backup strategy, backing up Nextcloud config, DB and files with restic into server local repo, which in turn syncs to another system and later to multiple offline HDD. I tested recovery from both online repo and offline repo archive using linux and windows which makes me think it should survive most of disaster I think about.
